70's Burgundy Micarta - Source?

[lambertiana]

Does anyone know where Buck sourced the burgundy micarta used on the 500 series from mid-70s to early 80s? I have wondered if it was Westinghouse but have never been able to find out.

They might have used multiple sources?

On the Buck site there is a place where you can ask historical questions. They might be able to help.
